I brown bag my lunch and with very rare exceptions, I pack a Hunt's Pudding Cup that I buy from Costco.
The 36 pack of these goes for 7.49, which is a bit over 20¢ each. That compares to 75¢ each for a Snickers bar out of the vending machine. Figuring in 250 work days per year and that is about $135 a year.
But there are more than just the monetary savings. A Snickers bar has 280 calories while the chocolate pudding has 130 calories and the chocolate-vanilla has 120 calories. Figuring out an average of 125 calories, that is a whopping 38, 750 calories per year you will save.
As I said in my post about the baked Lays snacks, this alone won't make you rich and thin, but it will help.
